ProTek R/C’s new Euro LS-5 .21 racing engine has been developed by top AMain and Novarossi pro drivers. Components were carefully selected to provide optimal power, run time and ease of tune.

The ProTek Euro LS-5’s composite carburetor resists heat, holds a consistent idle and is the choice of several elite pro drivers. The crankshaft and 5-port sleeve have been paired to provide linear power that produces a level of drivability that shreds lap times—throttle response is consistent throughout the entire RPM range.

ProTek R/C knows that fuel mileage and reliability are also critical; test drivers consistently ran nine and half to ten minutes per tank of fuel. Smoother drivers can easily obtain ten minutes or more between pit stops.

ProTek’s Euro LS-5 .21 is a unique competition-level racing engine, providing balance of power, efficiency and value. Replacement parts as well as optional headers and tuned pipes will be available through AMain Performance Hobbies.
